I mostly used apt-get but when I installed Ubuntu as a desktop OS, I used their store until I understood that Snaps were not always the officially packaged versions. The same thing with Flatpaks. I wanted to install Sublime Text so I looked to Flathub and found a package by Sublime HQ Pty Ltd. Imagine my surprise when went to Sublimes own website to saw that they offer it via apt-get (on Ubuntu/Debian), they even say on their forum that they do not provide via Flatpak or Snap.
Someone just uploaded a package using a name that looks official, while not actually being the owner of the product.
